The main role of hydraulic presses in the process of making personal protective vests and bulletproof vests

In the process of making personal protective vests/bulletproof vests, hydraulic presses (especially hot pressing hydraulic presses) play a key role, mainly used for material forming, lamination consolidation and structural reinforcement. The following are its core roles and specific applications:

1. Material forming (shaping)

Press flat high-performance fibers (such as Kevlar, UHMWPE) or ceramic/metal composite materials into ergonomic curved shapes (such as chest armor, back plate). Ensure that the protective plate matches the body curve, reduce wearing gaps, and improve protection efficiency and comfort.

2. Lamination consolidation (composite reinforcement)

Multi-layer bulletproof fibers (such as dozens of layers of Kevlar fabric) or composite materials (such as PE+ceramic) are pressed together under high pressure to eliminate air between layers and enhance structural density. Improve the impact resistance and energy dispersion of the material to avoid interlayer peeling during bullet impact.

3. Ceramic/metal armor plate molding

Pre-press or final press the ceramic (such as boron carbide, aluminum oxide) or metal (titanium alloy, steel) protective plate. Optimize armor geometry to improve ricochet probability and multiple bullet resistance.

4. Edge sealing and finishing

Laminate the edges of the formed protective plate or soft bulletproof layer to prevent fiber fraying (scattering) or water seepage.

In short, the core value of hydraulic presses in bulletproof vest manufacturing is:

✅ High material density through high pressure + high temperature (key bulletproof index)

✅ Precise molding of complex curved surfaces (improving wearing comfort)

✅ Efficient mass production (automatic pressing instead of manual lamination)
